DESCRIPTION:This code sets when the camshaft position (CMP) sensor signal is disrupted. MONITORED PARAMETER:Camshaft position sensor. TYPICAL ENABLING CONDITIONS:Engine idle MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:Engine idle PROBABLE CAUSES:1. Camshaft position sensor connector/harness.2. Camshaft position sensor.3. Improper timing or installation of the gear train, camshaft, or flywheel.

NOTE: If this SPN and FMI are active, verify that the wiring from camshaft position (CMP) sensor pin 1 to pin 44 of the motor control module (MCM) 120 – pin connector and that the wiring from camshaft position sensor pin 2 to pin 45 of the MCM 120 – pin connector is correct. NOTE: This code is set when the connector pins or wires are swapped for the camshaft position sensor.

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. Camshaft position sensor connector/harness.2. Camshaft position sensor.

NOTE: This may be due to an engine temporary running in a reverse direction. Symptoms include smoke exiting from intake manifold and a low idle speed, possibly due to a leaky injector. DESCRIPTION:This code sets when there is no match of camshaft and crankshaft signals. MONITORED PARAMETER:Camshaft reverse direction rising edge signal. TYPICAL ENABLING CONDITIONS:Engine state and low idle and camshaft reverse direction error. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% shutdown priority. VERIFICATION:Engine idle NOTE: If any other codes for camshaft, crankshaft, or oil pressure are active fix...
